We're dividing 470668 by 20 
We want to figure out the number of times 470668 can be divided by 20.

Advancing to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 20

On to step 2:
When dividing 47 by 20, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 47 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 20

Going ahead to step 3:
The number 20 fits into 70 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 23.0
If we take 60 away from 70, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 20

Going ahead to step 4:
If we divide 106 by 20, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Subtract 100 from 106 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 20

Let's proceed to step 5:
When dividing 66 by 20, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 2353.0
Subtract 60 from 66 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 20

Moving on to step 6:
The number 20 fits into 68 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 23533.0
If we subtract 60 from 68, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
20 goes into 80 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 23533.4
Subtracting 80 from 80 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23533.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23533.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 23533.4 and a remainder of 0.0.
